PIPE

Frank N. Mariani, New York, N. 'Y. Application April 25, 1940, Serial' No. 331,663 11 Claims. (01. 131215) Ihe present invention is directed to a functionally and structurally improved and serviceable tobacco smoking pipe of the type having a bowl mounted at the distal end of a relatively light weight and hollow metal shank provided exteriorly thereof with a plurality of longitudinally arranged and spaced heat radiating ribs and carrying at the proximal end thereof a conveniently accessible mouth piece portion. One object of the invention however is realized in the provision of a pipe of the type referred to wherein readily accessible control means is utilized to regulate the volume of smoke from the bowl to the mouth piece portion. Another object of the invention comprehends the provision of an exteriorly finned and relatively elongated hollow-shank constituting a support for the bowl and characterizing a bore desirably interrupted by transversely arranged bafile means dividing the bore intocommum'cating primary and secondary smoke conducting chambers to preclude drainage of moisture and/or products of condensation from the primary chamber into the secondary chamber and to the mouth piece portion. A further object of the invention is to provide a conveniently controlled manipulatable multiple rotary valve to permit or prevent smoke fumes from the bowl to be drawn into the primary chamber of the finned shank and concomitantly allow or prevent the smoke fumes in the primary chamber to be drawn into the sec ondary chamber and mouth piece portion. Further important objects, features, and functional and structural advantages of the invention for providing a relatively cool and dry smoke will appear from the following detailed description considered in the light of the accompanying drawing wherein:

Fig. 1 is a side elevational view of the pipe according to my invention.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a longitudinal sectional view of the lines33 of Fig. 1.

Fig. 4 is a fragmentary perspective and broken 'ew'of the finned shank showing in exaggerated fashion the multiple valve in an open relation.

Fig. 5 is a fragmentary broken view of the finned shank illustrating the multiple valve closed in respect to allowing smoke fumes to enter the primary chamber and closed to prevent smoke fumes from leaving the primary chamber to be drawn 'into the secondary chamber and mouth piece portion, and

Fig. 6 is a perspective view of the unitary control means embodying the multiple valve.

According to the invention, the tobacco smoking'pipebroadly designated l0 comprises a bowl H, aheat disseminating hollow metal shank l2, a mouth piece portion I3, and the smoke fume regulating smeans generall-y designated 1-4.

The bowl I I includes the tobacco receiving concavity l5 and has the fixedly secured hollow plug or socket L6 having an upper straight face 11 interrupted by a plurality of radially extending and inclined grooves l8 communicating with the coaxial opening 19 in .the plug and with the integrally merged and exteriorly threaded nipple 20 extending outside of the bowl which is provided with a bottom fiat face 2| in alinement with the fiat annular shoulder 22 of the plug.

Projecting upwardly from the upper wall 23 of the rectangularly shaped hollow shank I2 is the boss 24 having the upper flat face 25 and the interiorly threaded opening 26. With the nipple 2B screwed into opening 26, the alined faces 25 and 22 ultimately rest on and against fiat face or seat 25 of the boss which in fact constitutes a stop to limit the projection of the nipple therein, thus properly positioning the bow] in respect to the shank at the distal end of the latter.

The opening of the socket [6 however communicates with the cylindrical bore of the hollow shank I 2 or more particularly communicates with the saliva collecting and primary chamber 21 of the bore divided by the transversely arranged metal bafile or wall 28 integral with the walls of the body of the aluminum shank I2. Thi baffle is provided with an eccentrically disposed opening 29 permitting smoke fumes from the primary or distal chamber 27 to pass into the secondary or proximal smoke circulating chamber 36 in instances .of course where the spaced multiple valves of the regulating means are in an open relation as illustrated in Fig. 3.

Specifically however the smoke regulating means is provided with a cylindrical stem E3 which fixedly sustains at its proximal end the closure disc or valve 32 having notch or orifice 33 adapted to line up or register with opening 29 in the baflie 28 to allow the rising or circulatory smoke fumes to travel from the primaryto the secondary chambers 21 and 30 respectively.

Also, secured to and bodily rotatable with the slidable stem 3| of the regulating means is the closure valve .34 disposed intermediate the ends thereof and comprises a cam shaped member having a'circular end face 35 adapted to be revolved to closeor open the opening l9, thus constituting means to control the egress of fumes from the pipe bowl into the primary chamber, the arrangement being such that effective means for regulating the control of the smoke fumes from the bowl into the primary chamber and from the latter into the secondary chamber is alternately disposed on opposite sides of the stem 3|, thus permitting simultaneous control of the smoke fumes from the bowl and from the primary chamber,-since both of the spaced-valves are bodily actuated together-upon manipulation of the slidable-and rotatable regulating control means.

the knurled portion 4|, the flat face 39 having the indicia thereon for automatically indicating that the multiple valve is in its opened relation in respect to the baffie and bowl, the tapered portion 31 being frictionally but removably associated with the front tapered part 43 of the primary chamber 21.

Removably associated with the proximal end of the finned rib shank 12 or the tapered portion 44 of the secondary cylindrical chamber 30, is the frusto-conical distal end 45 of the mouth piece portion or stem l3 fixedly carrying the concentrically arranged tube or nipple 41 likewise concentrically arranged and removably projecting into the secondary chamber 39 of the elongated shank l2 which has on its front and rear side walls 48 and 49 the integrally merged and vertically spaced relatively thin heat dissipating or radiating ribs or fins 59 extending lengthwise of the shank.

In the assembled relation of the bowl, which may be of a suitable briar, the finned shank supports the bowl and the mouth piece portion while the control head 36 may be conveniently manipulated to rotate valve 34 to open the bore IQ of the plug II. This is accomplished by rotating head 38, thus bodily rotating the stem 3|, and the spaced valve members 32 and 34. Thus, smoke communication is established between the bowl and the primary chamber and since orifice 33 is now lined up or in registration with the eccentrically arranged outlet orifice 29 in the baffle 28, communication also is established between the primary and secondary chambers. It follows that by a single operation both of the valves 32 and 34 can be simultaneously actuated and controlled.

By the present arrangement, it is apparent that the extent of the opening of the outlet openings l9 and 29, may be varied or regulated to control the volume of the smoke fumes leaving the bowl and leaving the primary chamber since both of these openings can be only partially opened by manipulating the head 38, or in other words, a multiple cut off is provided and controlled by unitary means which is limited in its insertion into the primary chamber by the baffle 28 serving as a stop for the rotatable and slidable disc shaped valve 32.

Briefly recapitulating, it will be observed that the shank is a one piece relatively light weight rectangularly shaped hollow metal member preferably of aluminum which has a cylindrical bore interrupted by an apertured baffle dividing the bore into a primary and secondary smoke communicating chamber, and regulating means in the form of a multiple valve is provided for controlling the amount of smoke into the primary and secondary smoke conducting chambers simultaneously, the regulating means being likewise of a suitable metal such as aluminum, and preferably in one piece.

The bowl as shown is of wood and carries the metal socket 16 with the moisture collecting radial drainage slots 18 directing the products of condensation downwardly into the primary chamber where they are captured or retained against travel into the secondary chamber by the baflie 7 means 3. The smoke fumes are also processed in the primary chamber in that they are divided by the shank 3i and valve 34, hence products of condensation collecting thereon are trapped. The smoke fumes in the primary chamber are initially drawn downwardly therein and then flow upwardly through the partly or fully registering openings 23 and 29. It follows therefore that the smoke fumes entering the secondary chamber have been dried and cooled in that, a certain amount of heat therein is transmitted to the wall of the primary chamber to the outside fins or ribs 50 which tend to enhance the dissipation of the heat by radiation. Therefore the smoke fumes entering the secondary chamber have been previously cooled and these fumes are further cooled in the smoke circulating secondaryi chamber also by radiation because of the intermediate part of the metal shank and the outside ribs thereon. The smoke fumes conducted into the mouth stem through the nipple 41 are thus relatively dry and cool providing an enjoyable smoke to the user.

Since the bowl and the multiple valve and the mouth piece portion can be readily disconnected from the shank, the parts may be quickly inspected, cleaned, and conveniently reassembled. Moreover, since valve 32 fits closely but movably into the cylindrical primary chamber it may be considered as a piston having relatively sharp edges 5| utilized as scraping means for the interior of the bowl.

As many changes could be made in the above described construction and many widely different species or structural embodiments could be de vised without departing from the scope thereof, it is intended that all matter hereinbefore described in the specification and illustrated in the accompanying drawing shall be interpreted as illustrative not in a limiting sense.
